I’ve posted a video like this before, but Devour shared another video in Japanese showing a super-cooled magnet levitating a toy train.
Sort of being half serious here, but wouldn’t this CRY-AC-3 liquid nitrogen dispenser make just as good of a deterrent as mace or pepper spray? Also, had no idea chefs used this to freeze ice cream.
Is this ok to do? Seems awfully cruel to put a goldfish into liquid nitrogen.
